https://docs.dlocal.com/docs/india#cards seems support Amex, could just need to map the submethod?

I noticed that we have submethod warnings in the logs for successful payments also. For 175310978, which was successful, the logs show.
Apr 19 13:24:31 payments1005 dlocal_gateway: 175310978:175310978.1 The payment submethod [discover] was not found.

On the parent task @EMartin confirms that they don't support it in India right now, so let's treat it as a validation error and not let donors submit. We can use message donate_interface-error-msg-unsupported-card-entered to let the donor know they have to use a different type of card.

It would be nice to get the list of supported cards from the payment_submethods.yaml rather than hardcoding it in JS. I've just checked the list of cards we have seen authorized in India, and they are as follows: Mastercard, Mastercard Debit, Visa, Visa Debit, and Rupay.
